TINMANS TONGS.

SPECIFICATION formingpart of Letters Patent No. 256,556, dated April 18,1882.

Application filed January 9,7, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES R. EVERSON,

a citizen of the United States, and a resident of Macedon, Wayne county,New York, have invented certain Improvements in Tinmens Tongs, of whichthe following is a specification.

1 My invention relates to that class of tongs with broad flat bladesused for bending plates of tin in roofing or in the making ofeavestroughs; and my invention consists in constructing the tongs, asdescribed hereinafter, so as to bend up flanges of any requireddepthless or greater than that of the blades, and whether the edges of saidflanges are plain or ribbed.

In the drawings, Figure l is an edge view of my improved tongs. Fig. 2is a side view,and Fig. 3 a view showing the trough.

The legs H H are pivoted by the bolt ac, and

ble manner, but between the rivet and the blades d d are curved orspread apart, so as to leave a space, y, for the purpose hereinafterdescribed. The blades d d are long, narrow, 5

legs H E that they will lieflat together when said legs are closed, asshown in Fig. 1. Against guides s s on the blade d slide gages D D, eachhaving a lug, 0, extending over the upper edges of both blades, andsecured adjustably by screws f, which pass throughslots 12in the gages,as shown. I

The ton gs thus constructed are used in the ordinary manner 5 but. theextent of metal turned up to make the flange may be exactly determinedby setting the gages so as to leave between the lower edges of theblades and the lips c the distance equal to the depth of the flange tobe made. i

As ordinarily made, tinners tongs cannot be used for turning up flangesupon plates beaded above the latter are constructed in any suitabeveledat the lower edges, and so set on the or ribbed prior to bending. Byspreading the legs to leave a sp c 3/, between the same above theblades, I leave room for the reception of the bead, as shown, so thatthe plate 5 can be as readily bent as it it had a plain edge.

- The gages may be formed and secured adjust-ably in any'suitablemanner, and blades of any required forms and dimensions may be employed.0

By the use of this tool I am enabled to make a trough of the form shownin Fig. 3, the same consisting of a flat sheet havinga rib at one edgeand plain at the opposite edge, which may be inserted between theshingles while all the sheets are soldered flat together. Theabove-described tongs is then used to turn up the outer portion with itsrib at about right angles to .the part lying upon the roof, thus forminga -shaped trough, which will et'fect- 6o ively collect and conduct thewater, and which may be made and applied with less labor and expensethan those of the ordinary construc-' tion.

I do not here claim the trough or manner of making the same, as this mayform the subject of a separate application for Letters Patent.

I claim- A tinners tongs consisting of pivoted crosslegs H H and bladesd d ,the legs being spread apart above the blades, and the latter beingprovided with gages secured adj ustabl y to one blade and extending overthe upper edges of both, substantially as set forth.

Intestimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.
